如何获取网格GXT上所选复选框的行索引 [英] How to get the row index of selected checkbox on grid GXT

问题描述

我正在使用GXT（2.2.5），并需要获取网格上的chenged复选框的行索引。我正在做的是创建一个网格并应用GridCellRender在第一列中显示一个复选框，然后当任何复选框更改其值（在OnChange事件中的监听器）时，必须采取已更改复选框的行索引。这是我现在代码的一部分：

  checkColumn.setRenderer（new GridCellRenderer（）{
 @Override 
 public Object render（ModelData model，String property，ColumnData config，int rowIndex，int colIndex，ListStore store，Grid gri）{
 final CheckBox check = new CheckBox（）; 
 check.addListener （Events.OnChange，new Listener< BaseEvent>（）{
 @Override 
 public void handleEvent（BaseEvent be）{
 //这里我们得到行索引
} 
}）; 
 return check; 
} 
}）; 
  

谢谢。

解决方案你可以像这样得到它：

  checkColumn.setRenderer（new GridCellRenderer（）{
 @Override 
 public Object render（final ModelData model，String property，ColumnData config，int rowIndex，int colIndex，final ListStore store，Grid gri）{
 final CheckBox check = new CheckBox（）; 
 check.addListener（Events.OnChange，new Listener< BaseEvent>（）{
 @Override 
 public void handleEvent（BaseEvent be）{
 ////////// 
 int indx = store.indexOf（model）; 
 ////////// 
 $ b} 
}）; 
 return check; 
} 
}）; 
  

（请注意，您必须转换为最终您的商店和

或者这可能是： checkColumn.setRenderer（new GridCellRenderer（）{
@Override
public Object render（final ModelData model，String property，ColumnData config，int rowIndex，int colIndex，final ListStore store，Grid gri）{

final CheckBox check = new CheckBox（）;
check.setData（indx，store.indexOf（model））;

check.addListener（Events.OnChange，新的Listener< BaseEvent>（）{
@Override
public void handleEvent（BaseEvent be）{
//////////
int indx =（（CheckBox ）be.getSource（））。getData（indx）;
//////////
$ b}
}）;
return检查;
}
}）;

我希望这可以帮助

I am working with GXT (2.2.5) and need to get the row index of chenged checkbox on the grid. What i am doing is to create a grid and apply a GridCellRender to show a checkBox in first column, then when any checkBox change their value (listener at the OnChange event), the row index of changed checkbox must be taken. This is a part of my code by the moment:

    checkColumn.setRenderer(new GridCellRenderer() {
        @Override
        public Object render(ModelData model, String property, ColumnData config, int rowIndex, int colIndex, ListStore store, Grid gri) {
            final CheckBox check = new CheckBox();
            check.addListener(Events.OnChange, new Listener<BaseEvent>() {
                @Override
                public void handleEvent(BaseEvent be) {
                    //Here we get the row index
                }
            });
            return check;
        }
    });

Thanks.

解决方案

You can get it like this:

 checkColumn.setRenderer(new GridCellRenderer() {
        @Override
        public Object render(final ModelData model, String property, ColumnData config, int rowIndex, int colIndex, final ListStore store, Grid gri) {
            final CheckBox check = new CheckBox();
            check.addListener(Events.OnChange, new Listener<BaseEvent>() {
                @Override
                public void handleEvent(BaseEvent be) {
                    //////////
                    int indx = store.indexOf(model);
                    //////////

                }
            });
            return check;
        }
    });

(note that you must convert to final your store and model variables)

Or maybe this:

checkColumn.setRenderer(new GridCellRenderer() {
        @Override
        public Object render(final ModelData model, String property, ColumnData config, int rowIndex, int colIndex, final ListStore store, Grid gri) {

            final CheckBox check = new CheckBox();
            check.setData("indx", store.indexOf(model));

            check.addListener(Events.OnChange, new Listener<BaseEvent>() {
                @Override
                public void handleEvent(BaseEvent be) {
                    //////////
                    int indx = ((CheckBox) be.getSource()).getData("indx");
                    //////////

                }
            });
            return check;
        }
    });

I hope this helps
